How to enable DE based LCD using DM6446?

Other Parts Discussed in Thread: TMS320DM6446

Hi,

Thanks for your great support. I am using DM6446 Evaluation board with LCD. I can do programming for  HSYNC,VSYNC  based LCD. But i am not able to drive 8.4 inch DE based LCD panel. How do i generate DE signal from HSYNC  and VSYNC? (OR)  Is there any register setting to drive DE based LCD in VPBE unit? Please look at the below registor setting I have used.  and pixel clock is 36mhz.

VMOD=0X2013;  LCDOUT=0X3;  SYNCCTL=0XF;  YCCTL=0X00;   RGBCTL=0X00;   SYNCCTL=0XF;  OSDHADV=60; OSDCLK0=0X8;  OSDCLK1=0X1FF;

 

   m_pVencRegs->m_Hspls    =  52;   

    m_pVencRegs->m_Vspls    = 4;     

     m_pVencRegs->m_HInt     = 1024 ;  

    m_pVencRegs->m_VInt     = 625 ;    

    m_pVencRegs->m_HStart   =  110;  

    m_pVencRegs->m_VStart   =  10;   

    m_pVencRegs->m_HValid   =800;   

    m_pVencRegs->m_VValid   =600;

    m_pVencRegs->m_HSDelay  = 0;

    m_pVencRegs->m_VSDelay  = 0; 

The above setting are working in HSYNC and VSYNC based LCD. What changes I have to do to get the display on DE based LCD? P lease find the attached LCD datasheet for your referrence4807.8.4 inch sharp LCD---LQ084S3LG01_14_Aug_07.pdf
